交换各向异性与单轴各向异性之间的竞争使体系存在单稳态与双稳态两种不同的状态，直接决定了交换偏置的角度依赖关系。
It is found that the system will be in monostable state or bistable state, which is controlled by the competition between the uniaxial anisotropy and the exchange anisotropy of the system.
结果表明：随着双线性耦合场或双二次耦合场的增加，交换偏置场的最大值位置向易轴靠近。
The results show that the maximum of the exchange bias field departs from easy axis with increasing the biquadratic-coupling field or bilinear field.
